How to Calculate CGPA in Nigerian University

I remember in my first year at the University I and many of my classmates had no clue on how to calculate CGPA.

The calculation of CGPA at the University sounded like complex mathematics work. In fact, some persons had to pay for the calculation of their results.

Well, the calculation of CGPA is not a complex mathematics problem. It is easy and you can do it yourself.

In this post, I will be showing you the easy way that you can use to calculate the GPA for your first and second semesters.

You will learn how to calculate GPA from CGPA. Also, you will know how to calculate CGPA in Nigerian Universities like the University of Ibadan, UNN, AAU, UNILAG, NOUN, OAU, UNIPORT, UNILORIN, etc. and other tertiary institutions in Nigeria.

First-year and other students will find this post helpful. But first, let me explain the meaning of GPA and CGPA in Nigerian Universities.

Let me know in the comment box if you need clarifications. I will get back to you as soon as possible.

Nigerian University Grading System

The grading system in Nigeria tertiary institutions uses over a hundred scores.

Thirty (30) marks is for continuous assessment while seventy (70) is for examination score.

Here is the grading system for Nigerian Universities;

GPA

GPA stands for grade point average. It is the grade point for your first and second-semester results.

You need to know the score you got for each of your courses to calculate the GPA of either semester.

Below is a sample of the first and second-semester results of a first-year student in the University.

You will divide the total point by the total number of credit unit loads for the first semester.

Total Point = 63

Total Unit = 19

GPA = 63/19 = 3.32

You will divide the total point by the total number of credit unit loads for the second semester.

Total Point = 51

Total Unit = 15

GPA = 51/15 = 3.4

CGPA

CGPA stands for cumulative grade point average. It is an addition to your first and second semester GPA.

Now the final step is to add the GPA of both semesters and divide it into two (2) to get your CGPA.

SemesterGPA
First semester3.32
Second semester3.4
Total

CGPA = First semester GPA + Second semester GPA / 2

CGPA = 3.32 + 3.4 / 2 = 3.36

Final Year CGPA

The final year CGPA is an addition of your CGPA from the first year to your final year divided by the number of years of study.

Below is the CGPA of a student from the first year till the final year.
